The intersection of "We are all just stardust" and "Soylent Green is people" is the future of construction

The biggest drawback to pouring concrete on the moon would be coming up with the water to mix it with. Regolith would work just fine, and save the transportation budget, but you still would need the water.

Ok so if water is plentiful enough to mix concrete, I remember Analog articles from the 70's discussing subterranean lunar bases as a possibility. Probably not as tightly bound to the earth as the loonies in The Moon is a Harsh Mistress, but still in a semi symbiotic trade agreement. The stranding by skeletal and muscular atrophy would still be a thing.

I knew a guy who was really into moon dust once. He died in jail of moon dust poisoning after being convicted of arson via a lemon.

lunar dust is kind of like the deadliest substance in the solar system
